This paper presents a method to design foil sections for marine propellers or hydrofoils using inviscid and boundary-layer theory. The current configuration allows a variety of goals and constraints including cavitation inception prediction, lift/drag maximization, and flow separation avoidance. A state-of-the-art two-dimensional boundary-layer formulation is coupled with a perturbation potential panel method to determine the hydrodynamic characteristics of the sections. Several examples are designed using this method and are compared to conventional sections. The foil shape is optimized using a method of feasible directions algorithm.
